So I've got the DS1821+ setup using three 14tb drives. Now I have data from the old Windows server that's on 3x 4tb drives and 3x 2tb drives that I need to start copying over. My original plan was to install the drives from the Windows box into the Synology and copy everything locally, but it doesn't seem the Synology will mount NTFS drives internally, only via the USB interface. I got that from googling around, so please tell me if I'm wrong. I have to imagine it will take 1000x longer to do ~16tb of data via USB than doing it internally, but I'm new to Synology so I don't know. How would y'all go about transferring this much data over?

Do you have a decent network connection between the old windows server and the new Synology? (Or just a Windows machine if the old server has died). Transferring that way will likely be as fast as the drives can do.

For those that accept it, does Synology really care what m.2 drive you stick in there? I know they sell their own.

Transferring that way will likely be as fast as the drives can do. It's gigabit LAN. I mounted the Synology share on the old Windows machine and did a test, about 20 minutes for 85gb. So around 3 days worth of copying stuff that way, if I'm doing the math correct. Guess I'll be babysitting it for awhile.

EC posted:. So around 3 days worth of copying stuff that way, if I'm doing the math correct. True but that's within range of the maximum throughput of the drives in question. I don't think LAN transfer is slowing you down vs. locally connected read. You're gaining a lot of not worrying about filesystems etc and are using both devices as intended.

Depends on what you're doing and if you have it as a read-only or read/write cache Ours burned out an Intel SSD DC S4500, it was being used as a backup target in Veeam and it had write-caching turned on. Derp. My particular synology has a slot for either a 10gb card or cache SSD, but not both So we use SATA SSD's for cache drives.

You're gaining a lot of not worrying about filesystems etc and are using both devices as intended. It's going pretty well so far. I've got all the data off 3 of the 4 2tb drives. I'm worried about the last one as I was having some issues accessing it last week, but it seems to be working fine so far. Any good tutorials for learning and setting up Docker for stuff like SAB/Sonarr? I have a real basic, surface level understanding of what Docker is and why it's good to use it. According to the Sonarr discord there's no real way to migrate an install from a Windows box to a Synology, and I am dreading having to go in and adjust all the series and replicate everything. SAB should be easy, although it will be sad to lose the 11 years worth of history on the thing.

Yes, that's the point. It sucks up both slow and fast drives. You need the slow drives for long term storage, so all large storage is gone. You need as many fast NVME or SSDs as you can to trash through to write as much as possible, as fast as possible (to generate the bingo boards to put into the rotational drives), so all fast storage is gone. The min size requiring 300G+ means that 128/256GB SSDs are largely untouched, though

I'm decommissioning my old Unraid server which has a bunch of still working, if old disks. Is there a small enclosure or something similar I can get to either use these as a huge USB array or JBOD? Or just on the network is fine as a backup/no frills file storage device. I already have a Synology DS1819+ so that is doing all the heavy lifting for me already.

Then you only pay for one piece of plotting hardware that doesn't wear out and you could even have hot-swap bays for zero downtime plotting. Maybe that USB enclosure thing doesn't strictly work with throughput constraints but it'd be what I'd do if I was serious about touching the poop.

The min size requiring 300G+ means that 128/256GB SSDs are largely untouched, though So they design a whole new "thing" and instead of making it less insanely (with chunks that can be derived and signed in a standard chunk of memory and written once to disk) they've done it so it far exceeds anything but large servers, instead choosing to use basically large scratch disks - chewing through flash? RAM is built to constantly be re-written, and plenty of nerds these days have 16-32GB in their desktop, or computers which could be upgraded to that amount. Why not make it in 4 or 8gb "plots" ? I assume it's just so they don't have to store as much metadata on the blockchain, but you could also then have them built to be stitched together as they're written once to the disk. Sorry this just blows my mind that they saw a problem, thought "we could fix this!" and then just made it dumb in a different, less renewable way.

AlternateAccount posted:So then what's the expected break even ROI date for THAT? Less than a quarter if the rumors of chia destroying SSDs within weeks are true. As is usually the case with cryptocurrencies, what software engineers think is a limiting factor is something that accountants will work around. Bitcoin limited by energy turns into "arbitrage electricity prices, stealing energy outright where possible." If Bitcoin existed contemporaneously with Enron, they probably wouldn't have gone bankrupt. Chia is operating in the space that every cloud storage and big data company has already optimized down to slivers of margin. Once you know how to game opex/capex, amortization, and depreciation you can make very expensive things very cheap as long as the value of your product stays above a certain amount. xarph fucked around with this message at 23:22 on May 12, 2021 |

Calculations on the current price indicate if you buy 50TB of drives you could have them paid for in about a week. Now I've said that we'll see how many hard drives get destroyed. People are mostly concerned with SSD failures but what's going to happen to WD's SMR drives that are still out in the wild (and cheaper than the CMR versions so miners will buy them).

The load on the storage drives isn't that high, is it? You generate the plots on the SSD or in RAM, then write that info to the storage drives. Then you just have to read from them, to check for matches, right?
